Passinfg variables

skylineds

Hello,
My application needs to pass data stored in variables, within a form, one scrpt to another.
I create the following code for a test file 'test.php':
<html>
<body>
<form name="frmtest" method="post" action="test2.php">
<input type="hidden" name="avail" value="<?php echo($avail);?>" >
<input name="avail" type="checkbox">Check here<br>
<select name="frm_skApplicationProgrammer" size="1">
<option value="None">None</option>
<option value="Familiar">Familiar</option>
<option value="Light Skills">Light Skills</option>
<option value="Medium">Medium</option>
<option value="Strong">Strong</option>
<option value="Expert">Expert</option>
<option selected value="None">None</option>
</select>
<br><input type="submit" value="submit">
</form>
</body>
</html>

The code for 'test2.php' is as follows:
<html>
<body>
<?php
if ($avail == "on"):?>
checkbox value<br>
<?php
echo ($avail);
endif;
?>
<select name="frm_skApplicationProgrammer" size="1">
<option value="None">None</option>
<option value="Familiar">Familiar</option>
<option value="Light Skills">Light Skills</option>
<option value="Medium">Medium</option>
<option value="Strong">Strong</option>
<option value="Expert">Expert</option>
<option selected><?php echo "$frm_skApplicationProgrammer"; ?></option>
</select></td>
</body>
</html>

When I try this combination 'test2.php' tells me that the variables $avail and $frm_skApplicationProgrammer are unknown.
It worked until a couple of ays ago.
Who has the answer?

Chech your register_globals variable in the php.ini file, if it's OFF, set it to ON. If you are on public hosting, ask your hoster to do that for your site...

I dont see any code to get the parameters into the variables 😕

I always use this (for security):

Class GetVars{
/ public: construct valid inputs from GET or POST variables
requires track_vars = on */
function getVars() {
global $HTTP_POST_VARS;
global $HTTP_GET_VARS;
$vars = count($HTTP_POST_VARS) > 0 ? $HTTP_POST_VARS :
(count($HTTP_GET_VARS) > 0 ? $HTTP_GET_VARS : array() );
$cleanvars = array();
reset($vars);
while( list($var, $value) = each($vars) ) {
$cleanvars[$var] = $this->validateInput($value);

}
return $cleanvars;
}

/ private: sanitise a single variable /
function validateInput($var) {
if (get_magic_quotes_gpc()) {
$var = stripslashes($var);
}
$var = strip_tags($var);
$var = htmlspecialchars($var);
$var = str_replace("\n", " ", $var);
$var = str_replace("\r", " ", $var);
$var = trim($var);
return $var;
}

}
